Since the software development support apparatus disclosed in Patent Documents 1 and 2 is configured to automatically generate a program code from a block diagram, the work time of a programmer can be reduced. However, when creating a block diagram, it is impossible to grasp the performance as a program related to the block diagram. In other words, whether or not the block diagram is appropriately expressed so that a program code for realizing a desired process can be generated cannot be determined unless the program code is generated from the block diagram.
Non-Patent Document 1 describes the coding rules for program codes, and checks whether the program codes generated from the block diagram comply with the coding rules by using a commercially available tool as described above. I can. However, since Non-Patent Document 1 does not set rules regarding the notation of block diagrams, even when Non-Patent Document 1 is disclosed, at the time of creating a block diagram, grasp the performance as a program related to the block diagram. I can't.

As pointed out above, in the prior art, the program performance can be grasped only after the program code is generated from the block diagram. In the test after generating the program from the block diagram, if it is found that the program code is not described so as to achieve the predetermined performance, it is necessary to correct the block diagram to correct the program code. , Programming time will be longer.
Accordingly, an object of the present invention is to reduce the time required for programming and increase the work efficiency by detecting inappropriate notation in the block diagram before generating the program code from the block diagram.

  The present invention is a software development support apparatus in which a processing procedure is shown by a block diagram expressing a plurality of block elements and connection relationships between the block elements, and a program in a computer language is automatically generated based on the block diagram, Block diagram connection information extracting means for extracting, as target block diagram connection information, a plurality of block elements described in the block diagram and connection relations between the block elements, and a target block extracted by the block diagram connection information extracting means Target block diagram connection information storage means for storing diagram connection information, program generation means for automatically generating a program in a computer language from the target block diagram connection information, a plurality of block elements described and / or between the block elements For an NG block diagram in which the connection relationship of NG block diagram connection information storage means for storing block diagram connection information of the block diagram as NG block diagram connection information, and before the program generation means automatically generates a program in a computer language from the target block diagram connection information, The target block diagram connection information stored in the target block diagram connection information storage unit is compared with the NG block diagram connection information stored in the NG block diagram connection information storage unit. A block diagram coincidence determining unit for determining whether or not at least a part of the block matches the NG block diagram connection information.

  The software development support apparatus according to the present invention is realized by cooperating a general computer and software. That is, hardware resources such as computer input means, storage means, and arithmetic means are specifically operated by software to realize operation as a dedicated device.

  The input means accepts input by a user operation such as a keyboard and a mouse, input by a recording medium such as a floppy (registered trademark) disk, or input by an electrical signal such as a communication line or a LAN (local area network). Including means. The storage means is means for storing data such as characters and numbers, programs, and the like. For example, a random access memory or a hard disk in a computer. The calculation means is a numerical calculation means for executing a program. For example, it is generally called a central processing unit or CPU. A computer refers to an electronic computer including at least input means, storage means, and calculation means as described above.

  For example, GOOD block diagram connection information storage means for storing block diagram connection information of a GOOD block diagram expressed so as to satisfy the predetermined condition as GOOD block diagram connection information, and the stored GOOD block diagram connection information GOOD block diagram display means for displaying the GOOD block diagram based on the block diagram match determination means, wherein the block diagram match determination means determines that at least a part of the target block diagram connection information matches the NG block diagram connection information In addition, the GOOD block diagram display means displays a GOOD block diagram based on the GOOD block diagram connection information corresponding to the NG block diagram connection information.

  As an example, the block diagram creating means creates an NG block diagram creating means for creating and / or modifying the NG block diagram and / or creating a GOOD block diagram for creating and / or modifying the GOOD block diagram. Means. Moreover, you may comprise so that the target block diagram preparation means for preparing and / or correcting the block diagram by which the program is automatically generated by the program generation means may be provided.

  In the present invention, the NG block diagram connection information storage means stores in advance block diagram connection information of an NG block diagram that does not satisfy a predetermined condition as NG block diagram connection information. It is configured to determine whether or not at least a part of the diagram connection information matches the NG block diagram connection information. Since the NG block diagram is a block diagram that does not satisfy a predetermined condition, the notation of the block diagram corresponding to the target block diagram connection information that matches the NG block diagram connection information is an inappropriate notation. Thus, according to the present invention, since the program generation means can detect an inappropriate notation in the block diagram before generating the program code from the block diagram, the block diagram is corrected before the program code is generated. This makes it possible to reduce the time required for programming and increase work efficiency.

The target block diagram connection information extracted by the block diagram connection information extraction unit 5 is stored in the target block diagram connection information storage unit 6.

[Registration of NG block diagram and GOOD block diagram]
The software development support apparatus 1 registers in advance an NG block diagram in which notation that does not satisfy a predetermined condition is made, and compares the input target block diagram with the registered NG block diagram, so that the target block diagram is inappropriate. It is configured to detect the notation. Further, the present embodiment is configured to register a GOOD block diagram corresponding to the NG block diagram in order to show how to correct the detected inappropriate notation. The target block diagram creation screen 20 is provided with a menu button “NG / GOOD registration” 29 used when registering these NG block diagram and GOOD block diagram.

The flow of processing executed when “NG / GOOD registration” 29 is selected on the target block diagram creation screen 20 will be described with reference to FIG.
First, when the user selects “NG / GOOD registration” 29 on the target block diagram creation screen 20 (step 1), an NG / GOOD block diagram registration information screen is displayed (step 2).
An example of the NG / GOOD block diagram registration information screen is shown in FIG. The NG / GOOD block diagram registration information screen 30 includes an NG / GOOD block diagram registration information display unit 31 for displaying registration information, a menu button “new registration” 32 for newly registering an NG block diagram and a GOOD block diagram, A menu button “correct” 33 for correcting the registered information is provided.

When registering a new NG block diagram, “new registration” 32 is selected (steps 3 and 4 in FIG. 3). When “new registration” 32 is selected, an NG block diagram registration screen is displayed (step 5). An example of the NG block diagram registration screen is shown in FIG. The NG block diagram registration screen 40 includes a notation screen 43 for creating a block 42 and a wiring 42 for connecting the block elements, and various menu buttons.
As the various menu buttons, “block element selection” 44 for selecting block elements to be entered in the NG block diagram, “wiring” 45 for connecting the block elements, and the created NG block diagram A “GOOD registration” 46 for registering the corresponding GOOD block diagram is provided.

The user can create an NG block diagram on the notation screen 43 by appropriately selecting “block element selection” 44 and “wiring” 45 (step 6 in FIG. 3). The method for creating the NG block diagram using the menu buttons “select block element” 44 and “wiring” 45 is the same as the method for creating the target block diagram on the target block diagram creation screen 20 described above with reference to FIG. is there.
The NG block diagram creating means in the NG / GOOD block diagram creating unit 8 creates an NG block diagram based on data input by the user via the NG block diagram creating screen 40 and the input device 2. The block element 41 and the connection 42 between the block elements shown in the block diagram are extracted by the block diagram connection information extracting unit 5 as NG block diagram connection information. An example of the data structure of the NG block diagram connection information extracted from the NG block diagram shown in FIG. 5 is shown below.

Line ID, Line input block element (Type: ID), Line output block element (Type: ID)
SW001, (A: SF001), (B: SF002)
SW002, (A: SF002), (B: SF003)

As the data structure of the NG block diagram connection information, as in the target block diagram connection information, an ID (corresponding to SW001 to SW002 in FIG. 5) for identifying the solid of the line indicating the connection of the block element, and the input of the line Block element types (corresponding to A, B, and C in FIG. 5) and IDs for identifying solids (corresponding to SF001 to SF003 in FIG. 5), line output block element types and solids are identified. IDs are arranged in the order of flow in the block diagram.
After the user creates the NG block diagram as described above, when the “GOOD registration” 46 shown in FIG. 5 is selected (step 7 in FIG. 3), the GOOD block diagram registration screen is displayed (step 8). An example of the GOOD block diagram registration screen is shown in FIG. The GOOD block diagram registration screen 50 includes a notation screen 53 for creating a block 52 and a wiring 52 for connecting the block elements, and various menu buttons.

The menu buttons include “block element selection” 54 for selecting block elements to be entered in the GOOD block diagram, “wiring” 55 for connecting the block elements, and the created NG block diagram and GOOD. A “registration complete” 56 for storing the block connection information of the block diagram is provided.
Similarly to the creation of the NG block diagram on the NG block diagram registration screen 40, the user appropriately selects “block element selection” 54 and “wiring” 55 to create a GOOD block diagram (steps 9 and 10 in FIG. 3). ). The GOOD block diagram creation means in the NG / GOOD block diagram creation unit 8 creates a GOOD block diagram based on data input by the user via the GOOD block diagram creation screen 50 and the input device 2. The block element 51 and the connection 52 between the block elements shown in the block diagram are extracted by the block diagram connection information extracting unit 5 as GOOD block diagram connection information.
The data structure of the GOOD block diagram connection information is the same as the data structure of the NG block diagram connection information.
When “registration complete” 56 is selected after creating the GOOD block diagram, the NG block diagram connection information and the GOOD block diagram connection information extracted by the block diagram connection information extracting unit 5 are the NG block diagram connection information storage unit 9 and the GOOD block diagram, respectively. It is stored in the connection information storage unit 10 and registration of the NG block diagram and the GOOD block diagram is completed (steps 11 and 21 in FIG. 3). If the corresponding GOOD block diagram is not created after the creation of the NG block diagram, “registration complete” 56 is selected without creating the GOOD block diagram (steps 9 and 11). In this case, only the NG block diagram is registered.

  Next, the flow of processing in the case of correcting an already registered NG block diagram rather than creating a new NG block diagram will be described. In this case, the process flow proceeds from step 3 to step 12 in FIG. In the NG / GOOD block diagram registration information screen 30 shown in FIG. 4, the NG / GOOD block diagram registration information display unit 31 displays connection information of NG block diagrams and GOOD block diagrams that have already been registered. As an example, the display in the NG / GOOD block diagram registration information display unit 31 includes a check box 35 for selecting NG or GOOD block diagram connection information, and each NG / GOOD block diagram connection information as shown in FIG. A registration number 36 for identification, an NG block diagram connection information display 37, and a GOOD block diagram connection information display 38 are included.

The user checks the NG block diagram to be corrected and selects the menu button “correct” 33 (step 12 in FIG. 3). When “modify” 33 is selected, an NG block diagram registration screen 40 is displayed, and an NG block diagram based on the checked NG block diagram connection information is already displayed on the notation screen 43 (step 13). ). Similar to the creation of the NG block diagram described above, the user appropriately selects “block element selection” 44 and “wiring” 45 to correct the NG block diagram (steps 14 and 15). When the correction of the NG block diagram is completed, “GOOD registration” 46 is selected to shift to the work on the GOOD block diagram registration screen 50.
It is also assumed that the checked NG block diagram is not modified, and only the GOOD block diagram corresponding to the checked NG block diagram is created or modified. In this case, without correcting the NG block diagram on the NG block diagram registration screen 40, “GOOD registration” 46 is selected, and the process proceeds to the operation on the GOOD block diagram registration screen 50 (steps 14 and 16).

When “GOOD registration” 46 is selected, the GOOD block diagram registration screen 50 shown in FIG. 6 is displayed. On the notation screen 53, a GOOD block diagram is already displayed based on the GOOD block diagram connection information corresponding to the checked NG block diagram connection information. Similar to the correction of the NG block diagram described above, the user selects the “block element selection” 54 and “wiring” 55 as appropriate to correct the GOOD block diagram (steps 18 and 19).
When there is no GOOD block diagram connection information corresponding to the checked NG block diagram connection information, no block diagram is displayed on the notation screen 53. When creating a new GOOD block diagram corresponding to the checked NG block diagram, the user appropriately selects “block element selection” 54 and “wiring” 55 in the same manner as the creation of the GOOD block diagram in step 10 described above. Select to create a GOOD block diagram.

As described above, when the modification or creation of the GOOD block diagram is completed, the user selects “registration complete” 56 (step 20). If the GOOD block diagram is not modified or created, “registration complete” 55 is selected without performing any modification work after the GOOD block diagram registration screen 50 is displayed.
When “Registration complete” 55 is selected, the block diagram connection information of the modified NG block diagram and the modified or created GOOD block diagram is stored in the NG block diagram connection information storage unit 9 and the GOOD block diagram connection information storage unit 10, respectively. Thus, registration of the modified NG block diagram and the modified or created GOOD block diagram is completed (steps 20 and 21 in FIG. 3).

[Comparison of target block diagram and NG block diagram]
The software development support apparatus 1 compares the NG block diagram registered as described above with the target block diagram, and detects a notation that matches the NG block diagram from the target block diagram. Configured to detect appropriate notation.
The target block diagram creation screen 20 shown in FIG. 2 includes a menu button “NG detection” 28 for performing an operation of detecting inappropriate notation from the target block diagram.

FIG. 7 shows the flow of processing when “NG detection” 28 is selected.
When “NG detection” 28 is selected, the block diagram coincidence determination unit 11 causes the line input block element type, line output block element type and order thereof in the NG block diagram connection information, and target block diagram connection information. The type of the input block element of the line and the type of the output block element of the line and their order are compared (steps 30 to 32). In this embodiment, the comparison is performed in order from the NG block diagram connection information with the smallest registration number. The registration number of the NG block diagram is a number 36 for identifying each NG block diagram connection information illustrated in FIG.

As a result of the comparison, the block diagram coincidence determination unit 11 determines whether or not there is an element whose order matches the type of the block element (step 33). The matching block elements are highlighted (step 34). FIG. 8 shows an example in which matching block elements are highlighted on the block diagram creation screen. In FIG. 8, the matched block element 21 is highlighted by surrounding it with a broken line.
Next, when there is a GOOD block diagram corresponding to the NG block diagram to be compared, a small window 60 showing the GOOD block diagram including the block element 61 and the wiring 62 for connecting the block elements is displayed. (Steps 35 and 36). Note that a part of the target block diagram corresponding to the GOOD block diagram shown in the small window 60 (that is, a portion that matches the corresponding NG block diagram) is shown by a display frame 63. The processes in steps 32 to 36 are executed for all target block diagram connection information.

When the comparison with the NG block diagram connection information is completed for all the target block diagram connection information, the comparison between the NG block diagram connection information and the target block diagram connection information having the next registration number of the NG block diagram connection information for which the comparison has been completed. Comparison is performed (steps 37 to 39). In this way, all the registered NG block diagram connection information and the target block diagram connection information are compared, and an inappropriate notation is detected in the target block diagram, and the GOOD block showing the correct notation A figure is displayed.
When the user selects the menu button “automatic generation” 27 on the target block diagram creation screen 20 after correcting the inappropriate notation detected, the program code is generated by the program generation unit 7 from the target block diagram having the proper notation. Automatically generated.

As described above, in the software development support device 1, in the stage where the target block diagram is created, the “NG detection” process is executed, so that an inappropriate notation is generated from the block diagram before generating the program code from the block diagram. Can be detected and corrected. Therefore, it is possible to reduce the work time and to suppress the occurrence of mistakes such as overwriting of misrepresentations.
If a GOOD block diagram corresponding to the NG block diagram is registered in advance, the GOOD block diagram corresponding to the detected inappropriate notation is displayed. Thus, it is possible to immediately grasp whether the correction should be made, and the work time required for the correction is shortened.
Furthermore, since the software development support apparatus 1 can newly register or modify the NG block diagram and the GOOD block diagram as appropriate, it has an advantage that the expandability of the apparatus is high.
